How to uninstall?

I have tried to uninstall ispconfig with /root/ispconfig/uninstall but it gives this error:

Code:

houston2:~/ispconfig# ./uninstall
You chose to uninstall the ISPConfig system! Do you also want to uninstall the o
bjects (webs, users, databases, DNS entries etc.) created by the system? [y/n] y
Connected successfully

shell-init: could not get current directory: getcwd: cannot access parent direct
ories: No such file or directory
shell-init: could not get current directory: getcwd: cannot access parent direct
ories: No such file or directory

I can see that the data in /var/www/ still exist, so I would like to know, How do I tell what else is not restored correctly? after the uninstall... the /root/ispconfig/ directory is now deleted by the ./uninstall ...
